7 LAST FOR oo-rs OR SHOES.

SPECIFICATION forming part of Letters Patent No. 594,933, dated December7, [897. Application filed September 14, 1896. Serial No. 605,764. (Nomodel.) Patented in England January 12, 1895, No. 795.

obtained a patent in Great Britain, No. 7 95,

bearing date January l2,-1895,) of which the following is aspecification.

This invention relates to improvements in that class of lasts for use inthe manufacture of boots or shoes in which the heel and toe pieces aredivided. Hitherto many attempts have been made, with more or lesssuccess, to secure the separate parts of a so-divided last firmlytogether, so that when the said parts are put together and placed withinthe boot or shoe they will be rigid and even for hammering, lasting, andother purposes. Great difficulty has also been experienced either insecuring or looking the parts together or in releasing them when placedinside of the boot or shoe, pokers or other releasing-tools having to beemployed for separating the parts, thereby pulling the boot or shoe outof form.

Now the object of the present invention is to construct a divided lastso as to be easily and firmly put together, yet readily released and itsparts removed from the boot or shoe without stretching or displacing theupper and without using a poker or releasing-tool.

The present invention may be applied to an iron last; and it consists,essentially, in

combining one or more dovetails and singleor double interlocking catchesor hooks with a last, divided at such an anglethat in separating andreleasing, say the toe portion from the heel part, the former is causedto slide toward the heel-that is, within its total length-therebypreventing the stretching of the upper, a spring pin or bolt,hereinafter termed a spring-pin, being employed for the purpose ofpreventing the two parts from sliding apart.

In the. drawings hereunto annexed, Figure 1 is a part sectionalelevation showing the invention applied to an iron last; Fig. 2, a planof same, looking at the top; Fig. 3, a part plan of same, looking at thebottom'; Fig. 4, a part side elevation of the toe portion of an ironlast with this invention applied;

Fig. 5, an end elevation of Fig. 4; Fig. 6, a

side elevation of the heel portion of an iron last with this inventionapplied; Fig. 7, an end elevation of Fig. 6.

' According to this invention the last is divided, so far as thisinvention is concerned, into-two parts-that is to say, into a toeportion A and a heel portion B; but, if desired, the instep portion ofthe last may also be made loose, but in the drawings it is shown cast'onto the toe portion A. The last may be divided into the two portions Aand B at any suitable angle or angles, and I have found by experimentthat an angle such as, say, from about forty to about fifty orfifty-five degrees is the most convenient. The line a; 00 which dividesthe last into two portions is not made in one straight line entirelythrough the last. In the drawings at Fig. l the line a; w is drawn I attwo different angles to form a catch or hook C on each portion of thelast and hereinafter termed a hook -that is,the lower portion-of theline xocfrom the sole up to the hook is drawn at about an angle offortyone degrees andfrom the hook to the top of the last at about anangle of forty-seven degrees; but I wish it to be understood that I donot confine myself to these exact degrees, as they may be varied. Bythis means the hook O is strengthened; but, if desired, the two portionsof the line may be drawn at the same angle parallel to each other, orthe line 00 a; may be carried straight through the last at one angle, inwhich case the hooks 0 would require to be screwed or otherwise fixed tothe toe and heel portions. The hook O on the heel portion B should benotched in the form of a V, as shown at P, to fit a correspondingprojection P on the toe portion A for preventing any lateral movement atthe upper part of the said two portions. A dovetailed recess D, having Vsides in cross-section, as shown at Fig. 3, is also cast or otherwiseformed in the toe portion A, into which the projecting dovetail D onthe. heel portion B passes, care being taken that this part of theengagement only extends far enough to hold tion D, they are so firmlyheld together that no lateral or endwise movement of the parts can takeplace; but in order to prevent the two parts A and B sliding apartsaywhen the lasting operation is being performed as well as when the lastedboot or shoe is taken off the last stand or pivota vertical (or nearlyso) hole E is bored or east through the toe portion A at, say, about, ornearly so, a right angle to the sole of the last, and the vertical holeE is carried some distance into the heel portion B, as shown at Figs. 1and 6. The vertical hole E is preferably, though not necessarily, madeof two diameters. Into the vertical hole E is passed a pin F, encircledby a helical spring F, these two parts.

being hereinafter termed the spring pin or bolt F, so that its end willpass into the portion of the vertical hole E, located inthe heel portion13.; The spring pin or bolt F is arranged to project beyond; the top ofthelast, as shown, and its opposite end may be withdrawn from engagementwith the heel portion B by any convenient arrangement or devicesuch as,say, for instance, bya knob or head F (shown in dotted lines at Fig. at)or by a cord passed through the hole F (also shownin dotted lines atFig. 4,) why means of the device shown in the drawings, in which thespring-pin F is armed at its upper end with the projection G and soarrangedthat: its under surface 9 acts upon a cam-pathta,

cast, out, or otherwise formedin or on the toe portion A. Theprojection. G is passed through the hole H, cast or formed in the toeportion A, and which is made to communicate with the vertical hole E.VV-hen [the projection G is passed through the hole H and. turned at,say, a rightangle thereto,.it per,- forms the double function of,-first,preven ting thespring-pin F working out of position, and, secondly, ofwithdrawing the said spring pinfrom engagement with the heel portion 13when pulled orrotated on the cam-path a.

I is a hole formed in the last for the reception of the last stand orpivot.

To remove the divided last from the boot or shoe, the spring-pin F isfirst Withdrawn,

as herein-before described, from its engagement with the heel portion B,and as soon as the heel part of the lasted boot or shoe is raised thetwo portions A and B of the last will readily and easily slide apartwithout stretching the upper and without using a poker or releasing-toolfor separating the two parts of the last;

Having now described the nature of my invention, What I claim, anddesire to secure by Letters Patent, is-

Ina boot or shoe'lastdivided ilranangular and interposed hookeddirection, the combination therewith of aprojecting dovetail D on theheel portion, andarrecessDon engages, alvei'tical spring-pinF armed withaqcam-piece G for locking the two parts-oft the last together, and acam-pathmformed on the. toe portion A and on which the said: pieceoperates, all arranged substantiallyas hereinset'forth.

In. testimony. whereof I have hereunto :signedmy name to thisspecificationin presence ofatwo subscribing witnesses.
